Padatan Tersuspensi dan Terlarut Total

Padatan tersuspensi total atau Total Suspended Solid (TSS) adalah bahan-bahan tersuspensi dan tidak terlarut dalam air, bahan-bahan ini tersaring pada kertas saring Millipore dengan ukuran pori-pori 0,45 μm. Sedangkan Padatan terlarut total adalah bahan-bahan terlarut yang tidak tersaring dengan kertas saring Millipore dengan ukuran pori-pori 0,45 μm. Cara pengukuran TSS dilakukan dengan gravimetric yang terdiri dari kegiatan penyaringan, penguapan dan ...

Tide

Attach a low-frequency wave and in general the intensity of the smaller of the two times a day. This tidal movement caused by gravity from celestial bodies to the mass of water on earth. This movement is also influenced by the rotation of the earth itself as well as the layout of the island and the continent. Therefore, the high ...

Oxygen Levels and Solubility

Decreased levels of oxygen. Basically the process of reduction of oxygen in the water caused by the process of chemistry, physics and biology, namely:  The process of breathing (respiration) either by animals or plants.  The process of decomposition (decomposition) of organic material.  Basic waters are reducing. The basis of these waters can only be covered by only ...

Effect of Water Against Bentos

How to determine the water quality based Benthos in these waters one of them is with a qualitative approach where we look at the types than Benthos that live in the water itself. The types of benthic waters based on the degree of damage put forward by Mulyanto (1995) as follows: a) waters clean is Planaria, Perla, Isoperia, Leuctra, Nemoura, ...

Watershed

Generally Watershed (DAS) can be defined as an area, which is bounded by natural boundaries, such as a ridge or a mountain, or limit aid such as road or embankment, where the rainwater that fell in the region contributes flow to the control point (outlet ) (Suripin, 2002). Watershed is a geohydrology basin bounded by water and fishing area drained ...
